Nice looking Bike

But R4 normally refers to converted FZR 400's

Yeah, there is maybe other conversions named R4, but to me this one is R4. Its racing style Yamaha with about 400cc engine. Here is some newer pics. With this set up i have drive about 1000km, and it really is R4 on little willage roads.

http://www.mp-foorumi.com/gallery/gallery.php?user=Willevil&gid=0


Set up is:


Cub cylinders 421cc with Pro Design Cool head, own dome design
Keihin 35mm carbs with Duncan racing in take set with pyramid reeds and BMC air filters
Own chambers with NK super cool cans
Zeeltronic ignition

Front end with wheel and brakes from ZXR-400
Also levers and switches from ZXR-400

Rear wheel and brake also from ZXR-400
Swing is widened and strenghtened from std.
Rear shock from R6
Steering damper from R1
Also foot rests from R1

Bug spoiler is from GPZ500
Rear fairing from R6
Fucking front fender from Yamah RD350, cant find ZXR fender

Something else, but cant remember now......

edit. Tires are Battlax BT090 120/70 front and 160/60 rear, and these are unbelieveble good to drive....

Very cool bike, I like it. Cool Must be lots of fun to ride. Mr. Green How do you like the performance of the 421 Cub, like rideing around town in stop and go traffic? So now, would you recomend to someone else to get the Cub or would the Cheetah with power valves be better for daily rideing?
Thanks, Dave

Bike looks cool now. Very Happy It's amazing what only the wheels and forks do, it becomes a totally different bike!
